Horizontal Vacuum Purge Nitriding / Soft Nitriding Treatment Equipment RAV-N Type
Real-time atmospheric automatic control enables high-quality nitriding treatment!
This is a nitriding and soft nitriding treatment device equipped with the nitriding potential control unit "NITRONAVI" manufactured by Parker Heat Treatment Co., Ltd. By controlling the nitriding potential [KN value] with NITRONAVI, it is possible to selectively control the steel surface to a compound layer-free state, gamma prime phase (γ' phase), and epsilon phase (ε phase). Advanced feedback control allows for real-time management and the ability to save processing history data. **Features** - Achieves low cost, short delivery times, and high reliability due to a high standardization rate. - Flexibly responds to unique needs with a wide range of options. - Provides recipes that realize optimal material properties. - Support for stable operation by service engineers from Hirotsuki and Parker Heat Treatment Co., Ltd.
basic information
It consists of the Hirotsuku Manufacturing vacuum purge-type horizontal nitriding furnace "RAV type" and the Parker Heat Treatment Industry Co., Ltd. nitriding potential control unit "NITRONAVI." This combination allows us to maximize the potential of nitriding treatment while addressing challenges such as reducing environmental impact and securing labor, in addition to meeting the needs for high quality and cost reduction. We also provide recipes tailored to the product characteristics required for various steel products, such as wear resistance, corrosion resistance, and fatigue resistance. Please feel free to contact us.

Applications/Examples of results
Gear components, etc.: High fatigue strength → Low noise, process simplification (due to γ’ phase transformation) Springs: High fatigue strength/high toughness (high reproducibility compound layer control (KN control (lower))) Aircraft components, etc.: Control of compound layer thickness/voids (KN-KC control *also has needs for wear resistance) Stainless steel components: Surface delamination suppression/optimization of nitrided layer thickness Molds (die casting, cold forming): Cost reduction (alternative to special nitriding)
